A Multi-disciplinary Team

Since 2002, Accountable Aging has provided professional care management services to address the unique needs of older adults and those living with disabilities. Our interdisciplinary team relies on experienced professionals from diverse backgrounds including gerontology, social work, nursing, mental health, home care, facility administration, home health, hospice, and government benefits programs.

Our entire team is motivated by deeply personal experience in managing care for our loved ones. We’re passionate about helping others and serving our clients with the same conviction we served our own family members.
